Test of our Primary Hypothesis. Because this project involves a longitudinal design with 2 conditions measured at multiple times we will use mixed modeling to test our primary hypothesis. This approach will allow us to compare the SC and CALM-D conditions on the trajectory of change on our primary (i.e., BDI, weight, HbA1c, medication adherence) variables. Additionally, the mixed model allows us to incorporate relevant covariates into our specified models. (See Core D, for a fuller description of our modeling).
